EPA Adds Four Hazardous Waste Sites in the Southeast to Superfund’s National Priorities List, Proposing an Additional 3 Sites

(ATLANTA – March. 13, 2012) The U.S. Environmental Protection Agency has added four new hazardous waste sites in the southeast that pose risks to human health and the environment to the National Priorities List (NPL) of Superfund sites. EPA is also proposing to add another three sites to the list. Superfund is the federal program that investigates and cleans up the most complex, uncontrolled or abandoned hazardous waste sites in the country.

EPA is also withdrawing its earlier proposal to add the Arnold Engineering Development Center site in Coffee and Franklin Counties, Tennessee to the NPL. This site is being addressed under the Resource Conservation and Recovery Act (RCRA) program. Cleanup is progressing successfully, the migration of contaminated ground water is under control and measures have been taken that are protective of human health.

Since 1983, 1,661 sites have been listed on the NPL. Of these sites, 359 sites have been cleaned up resulting in 1,302 sites currently on the NPL (including the nine sites added today). There are 62 proposed sites (including the 10 announced today) awaiting final agency action.

With all NPL sites, EPA works to identify companies or people responsible for the contamination at a site, and require them to conduct or pay for the cleanup. For the newly listed sites without viable potentially responsible parties, EPA will investigate the full extent of the contamination before starting significant cleanup at the site. Therefore, it may be several years before significant EPA clean up funding is required for these sites.

Contaminated sites may be placed on the list through various mechanisms:

· Numeric ranking established by EPA’s Hazard Ranking System

· Designation by states or territories of one top-priority site

· Meeting all three of the following requirements:

- The Agency for Toxic Substances and Disease Registry (ATSDR) of the U.S. Department of Health and Human Services has issued a health advisory that recommends removing people from the site;

- EPA determines the site poses a significant threat to public health; and

- EPA anticipates it will be more cost-effective to use its remedial authority than to use its emergency removal authority to respond to the site.
